Abstract

Spin moments were derived from the magnetic-Compton profile of UFe2 which was measured using 59.38 keV circularly polarized synchrotron radiation from the Accumulation Ring Source at KEK, Japan. Although the net moment on the uranium site is no more than a tenth of a Bohr magneton, the individual spin and orbital moments, which are coupled antiparallel, are much larger and it is the spin moment that can be determined in magnetic-Compton scattering. The data have been analyzed in terms of the U 5f, Fe 3d and delocalized spin moments. The observed uranium-5f spin moment is less than half(i.e., <0.25 mu(B)) and the diffuse spin moment more than double (i.e., >0.20 mu(B)) those predicted from theory. These values compare favorably with those deduced from neutron measurements of the total magnetization.
